PROF STEPHON ALEXANDER
Big Bangs, Big Crunches and Big Bounces… physicists are questioning how the Universe began.

THE POWER OF HABIT
Whether they’re good or bad, habits can have a profound effect on your life. But understanding a little of the psychology behind them, can help you make or break them.

DISASTER WAITING TO HAPPEN
The space around Earth is filling up with satellites, both functional and defunct, jeopardising our continued use of it. But there are plans afoot to clear up the potentially catastrophic mess..

WHAT SHOULD I DO IF I GET STRANDED ON SNAKE ISLAND?

Just off the coast of southern Brazil lies the island of Queimada Grande, known as 'Snake Island'. Covering just 43 hectares (106 acres), this rocky island is home to between 2,000 and 4,000 highly venomous golden lancehead vipers (Bothrops insularis), which can grow to 70cm (just over 2ft). The snakes were trapped there around 11,000 years ago, at the end of the last ice age, when rising sea levels cut them off from the mainland.

DEAR DOCTOR : WHY DO I CATASTROPHISE SO MUCH AND HOW DO I STOP?

Catastrophe-filled thoughts are common, especially for people prone to anxiety. You might find yourself imagining that your first day at a new job will be an excruciating disaster, that you'll flunk an upcoming exam, or that your flight to New York will crash. These thoughts are unpleasant, but they're essentially your mind working overtime to keep you safe. If you start to act on these catastrophic thoughts, trying to avoid any risk in your life, that's when this thinking style can start to become debilitating.
